The ATP Auckland quarterfinals are set to ignite with some thrilling matchups, and one clash in particular is poised to steal the spotlight: Ben Shelton vs Sebastian Baez. But here’s where it gets intriguing—while Baez boasts an unblemished 3-0 record against American players this season, Shelton holds the edge in their head-to-head, having won their only encounter in this very tournament three years ago. Who will advance to the semifinals? Let’s dive into the predictions.
Luciano Darderi vs Marcos Giron
Head-to-head: Darderi 1-1 Giron
At first glance, Darderi’s record on fast surfaces might raise eyebrows, but don’t let that fool you. The Italian just pulled off a stunning comeback against former Auckland champion Alejandro Tabilo, rallying from a set and a break down. However, Giron presents a tougher challenge. The American has been on fire this season with a 5-1 record, his only setback coming in a semifinal loss to eventual champion Alexander Bublik in Hong Kong. While Darderi has shown remarkable improvement over the past year, Giron’s hard-court prowess might just tip the scales in his favor. But here’s the controversial part: Could Darderi’s momentum and fighting spirit flip the script? Only time will tell.
Prediction: Giron in 3
Fabian Marozsan vs Eliot Spizziri
Head-to-head: First meeting
Marozsan has been on a tear since May 2023, winning at least half of his 31 matches against Top 20 players, including a jaw-dropping upset over Carlos Alcaraz in Rome. His straight-sets victory over Casper Ruud earlier this week further cemented his status as a force to be reckoned with. Spizziri, however, is having an equally impressive run in Auckland. He’s yet to drop a set, dispatching Adrian Mannarino and Nuno Borges along the way. His game is evolving, and his confidence is soaring. And this is the part most people miss: While Marozsan’s endurance is legendary, Spizziri’s rising self-belief could be the X-factor in this matchup.
Prediction: Spizziri in 3
Jakub Mensik vs Giovanni Mpetshi Perricard
Head-to-head: Mpetshi Perricard 2-0 Mensik
Mensik’s three-set victory over Medjedovic in the previous round was a marathon, delayed by rain and completed under the lights. Both players pack a punch with their high-impact swings, and this match promises to be a slugfest. While Mensik’s power is undeniable, Mpetshi Perricard’s impeccable timing and court compression with his forehand have been standout features this week. But here’s the question: Can Mensik overcome the head-to-head deficit and turn the tide? It’s a toss-up, but Mpetshi Perricard’s consistency might just give him the edge.

Ben Shelton vs Sebastian Baez (Revisited)
Head-to-head: Shelton 1-0 Baez
Baez’s start to the season has been nothing short of phenomenal. He went undefeated in the United Cup and secured the biggest win of his career against Taylor Fritz. His 3-0 record against Americans in 2026, including wins over Emilio Nava and Jenson Brooksby in Auckland, speaks volumes. While Baez may not match Shelton’s firepower, his smart serving and improved return game—marked by increased aggression—have elevated his play. Shelton’s serving prowess is undeniable, but Baez’s persistence could force a tight contest. The burning question: Will Baez’s newfound confidence be enough to level the head-to-head, or will Shelton’s power prove too much to handle?
Prediction: Shelton in 3
What do you think? Will Giron’s hard-court dominance hold, or can Darderi pull off another upset? Is Spizziri ready to take down another giant in Marozsan? And who’s your pick in the Shelton-Baez rematch? Let us know in the comments—we’d love to hear your take!
